Shot glass or pipe with mechanical counter

ABSTRACT

A shot glass or pipe includes a counter in the form of a sleeve rotatably coupled to a main body or stem of the shot glass or marijuana pipe, the sleeve including a window through which a number indicative of the number of units of alcohol or marijuana consumed is visible. A ratcheting mechanism prevents reverse rotation of the sleeve, and ensures that the window stays in place in front of a particular number until the user intentionally applies force to rotate the sleeve to a next number.

This application claims the benefit of U.S. Provisional Patent Appl. Ser. No. 62/983,948, filed Mar. 2, 2020.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The invention relates to implements, such as a drinking glass or pipe, for consuming intoxicating substances.

The implements are combined with a counter that enables the user to keep track of the number of units of the intoxicating substance that have been consumed.

In a preferred embodiment of the invention, the intoxicating substance is alcohol, and the alcohol units tracked by the counter are “shots.”

In another preferred embodiment of the invention, the intoxicating substance is marijuana, and the units being tracked are “hits” or “drags” (i.e., smoke inhaled in a single breath).

2. Description of Related Art

A shot is a small amount of alcohol, often in the form of a distilled liquor and ranging in volume from approximately one ounce to 1.5 ounces, that is typically consumed in one gulp. The intoxicating effect of the alcohol and the rapidity with which shots can be consumed may cause a person to lose track of the number of shots, with the result that the person may inadvertently drink more than desired, and experience effects of excess alcohol consumption. A similar effect can occur when a person is smoking marijuana from a pipe. The intoxicating effects of the marijuana can cause a person to lose track of the amount of marijuana consumed, so that the consumer may consume more than desired. The present invention provides a way for the consumer to track the number of units of intoxicating or psychoactive substance consumed, even as the effects of the intoxicating substance affect the user's dexterity and/or judgment, to prevent the consumer from inadvertently consuming too much of the substance. While alcoholic drink counters are known, the counters have either been designed for purposes other than to enable a consumer to track consumption, or have involved complex mechanisms and electronics. Counters for tracking marijuana consumption are not currently available.

For example, it has previously been proposed to provide mechanical “drink” counters that enable a bartender to keep tab of drinks consumed from a beer stein, or that enable the user of a water bottle to ensure adequate hydration. However, the previously-proposed mechanical drink counters are ill-suited to counting alcoholic shots since they require a degree of sobriety to read and manipulate without error, and in general are too large and complex to fit on a shot glass.

By way of example, the mechanical drink counter proposed in Austrian Publication No. AT51859 involved a tube filled with balls and attached to the handle of a large beer stein, the counter requiring activation of a plunger mechanism to eject a ball into a container upon filling the stein, with the increasing number of balls in the container corresponding to the number of beers consumed. Not only was this counter too large and complicated to fit on a shot glass, but activation of the plunger and counting the number of expelled balls would be difficult for an alcohol-impaired person. On the other hand, U.S. Pat. No. 5,492,246 disclosed a counter in the form of a numerical dial indicator in the handle of a cup holder designed to removably receive multiple cups. While useful for monitoring consumption of beverages such as water over an extended period, during which multiple cups or glasses may be used, placement of the counter in the handle of the cup holder limits the counter to being relatively s difficult to read and manipulate, particularly for an alcohol-impaired person.

Indicators or counters specifically designed to count alcohol shots have also been previously proposed, but the problem of ensuring that the counter can be manipulated and read as the user becomes increasingly impaired has been approached by forgoing the simplicity of a mechanical counter in favor of complete automation of the counting process, so that the drinker is not involved in the counting process. As a result, the known shot indicators or counters are relatively complex and expensive, utilizing complicated electronic sensors and displays to overcome the difficulties in reading and manipulating mechanical counters. Shot glasses typically have a relatively thick base to withstand the shock of being slammed against a table or bar top after a shot is consumed, and thus any counter incorporated into the shot glass must be similarly able to withstand shocks, as well as to withstand being heat and immersion in soapy water during dishwashing. One such previously proposed electronic shot counter is the one disclosed in International Patent Publication No. WO 2017/165528, which describes a “shot glass” that uses an orientation sensor to detect the number of drinks taken from the shot glass and automatically control a numeric or graphic display, either on the glass itself or through a wireless connection to an external device.

An alternative approach to shot counting is disclosed in U.S. Patent Publication No. 2014/0354407, which describes a drink counter on a wristband. In one embodiment, a window is manually moved around the circumference of a that has been printed with numbers 1-12 to indicate the number of drinks consumed. While the use of a wristband avoids problems relating to physical abuse or liquid immersion of the shot glass, a drinker's focus tends to be on the glass itself and not on the person's wrist, making it increasing likely that the drinker will forget to implement the counter. In addition, getting drinkers to wear wristbands presents logistics problems that are not present if the counter is on the glass itself,

Of additional interest as background are U.S. Pat. No. D587,068, which shows a cup with a sleeve that is rotated around the circumference of a cup to indicate the type of beverage, but not the number of beverages consumed, as well as U.S. Pat. Nos. 8,177,437 and 8,739,972, and U.S. Patent Publication No. 2013/0008941, each of which discloses a beverage container sleeve that includes an automatically-incremented display of the number of times a beverage container, such as a beer can or water bottle, is placed into the sleeve.

Also of interest as background are Japanese patent publication number 20191198393, which discloses a “toast counter” that counts the number of toasts by somehow using radio waves and/or capacitive sensing to detect the level of liquid in a glass, and U.S. Pat. No. 6,419 384, which discloses a shot glass with an ornamental “indicator” in the form of a light bulb or speaker activated by an inertial switch.

Finally, German Patent Publication No, De 10201804744 discloses a drink counter based on measurement of liquid volume consumed per unit time. The indicator disclosed in this publication, unlike the shot counter of the present invention, is intended not for safety but to reward “drinking performance.”

SUMMARY OF THE INVENTION

It is accordingly an objective of the invention to provide a device for enabling a user to monitor consumption of intoxicating substances, and in particular to keep a running count of the number of units of the intoxicating substance that have been consumed by the user.

It is a further objective of the invention to provide a counter that is easy to manipulate and read by an intoxicant-impaired user.

It is a third objective of the invention to provide a counter that can be combined with an implement for consuming an intoxicating substance, that is simple and inexpensive, and that does not require any sensors or electronic circuitry.

It is a fourth objective of the invention to provide a drink counter that can be included in a shot glass or pipe.

These and other objectives are achieved, in accordance with preferred embodiments of the invention, by providing a shot glass with a mechanical counter that can easily be incremented by the user each time a shot consumed, and that provides a clear indication of the total number of shots.

In the preferred embodiments, the counter is made up of a series of numbers, symbols, and/or drawings extending around the main body of an implement for consuming an intoxicating substance, and a sleeve rotatably attached to the main body, the sleeve including a window for viewing a different one of the numbers, symbols, and/or drawings each time the sleeve is rotated relative to the main body. After each unit of intoxicating substance is consumed, the sleeve is rotated to change the number, symbol, or drawing visible through the window. In a preferred embodiment, numbers are arranged in ascending order, and rotation of the sleeve following consumption of a substance unit increments the number to keep a running count of the units consumed.

In order to ensure an accurate count, the invention provides a ratchet mechanism for preventing the user from unintentionally decrementing the intoxicant unit count, for providing a tactile indication that the count has been incremented, and for ensuring that the window will remain in front of a particular number until a force is applied to intentionally rotate the sleeve and thereby increment the count.

In the preferred embodiments of the invention, the ratchet mechanism includes a plurality of notches and an equal number of detents or pawls arranged to engage the notches when the window is positioned such that one of the numbers is centered in the window. The notches and/or the pawls are shaped to permit rotation of the sleeve is a single direction.

In preferred embodiments of the invention involving a shot glass, the notches are situated in a base of a shot glass, around a lower section of the shot glass, or around a midsection of the shot glass, with the pawls being extending from the sleeve and the sleeve fitting over the base or around the midsection of the shot glass, and the window and numbers positioned accordingly. It will be appreciated, however, that the illustrated positions of the notches and pawls is not to be taken as limiting.

In addition, in the preferred shot glass embodiments, the notches may be arranged on the sleeve with the pawls extending from the shot glass, or alternating notches and pawls may be arranged on both the shot glass and the sleeve. Furthermore, in embodiments in which the ratchet mechanism is on the lower portion of the shot glass, the sleeve may be cup shaped to fit over the bottom of the shot glass and retained by a central fastener and bearing to permit rotation. Alternatively, the sleeve may be in the form of a ring that fits within a corresponding grove in a midsection of the shot glass.

In an alternative embodiment in which the implement by which the intoxicant is consumed is a pipe and the consumption units to be tracked are marijuana hits, the counter may include a sleeve and ratchet mechanism mounted on a section of the pipe, such as on the pipe stem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 shows a shot glass with a drink counter constructed in accordance with the principles of a first preferred embodiment of the invention. The shot glass includes a shot glass main body 30 and an indicator sleeve 31 fitted onto and rotatably coupled to the shot glass main body 30 to form a shot glass/counter assembly.

In this embodiment, the shot glass main body 30 and sleeve 31 include a ratcheting mechanism that extends along generally vertically extending side surfaces rather than horizontal surfaces of the main body 30 and sleeve 31. As illustrated in FIG. 2, the shot glass main body 30 is frustoconical in shape and also includes an upper section forming a collar 32. The upper section 45 and the lower section 46 together form a continuous frustoconical inner surface 44. The outer diameter of the lower section 46 is reduced by an amount that is equal to a thickness of the sleeve 31, so that when the sleeve 31 is fitted over the main body 30, as shown in FIGS. 5 and 6, the outer body of the shot glass also forms a continuous frustoconical outer surface.

As illustrated in FIGS. 1 and 2, the lower section 46 of the main body 30 includes a series of numbers 33 arranged around the external circumference of the main body 30, in an area covered by the sleeve 31. These numbers are positioned so that they can be viewed through a window 34 in the sleeve 31 when the sleeve 31 is assembled to the main body 30. As the sleeve 31 is rotated around the main body 30, different numbers will appear in the window 34, the adjacent numbers differing in the illustrated embodiment by 1 to increment the count appearing in the window 34 as the sleeve 31 is rotated. Those skilled in the art will appreciate that the numbers 33 may take any form, including numbers that are engraved or physically formed in or on the main body 30, and/or printed, painted, silkscreened, or otherwise drawn on a surface of the main body, or provided in the form of stickers. In addition, it will be appreciated that the numbers are not limited to Arabic numerals, and that the numbers may further be replaced or supplemented by pictures or symbols that represent the effects or consequences associated with the number of shots that have been consumed.

To ensure that the count is advanced by just one step each time the sleeve 31 is rotated relative to the main body 30, and thereby make it simple for a user to increment the counter even when impaired or intoxicated, the shot glass of the embodiment illustrated in FIGS. 1-8 includes a ratcheting mechanism made up of cooperating pawls 35 and notches 37. Pawls 35 extend downwardly and inwardly from an interior surface of a base 36 of sleeve 31 to form tines that engage notches 37 in the exterior surface of lower section 46 of main body 30. Pawls 35 may be formed by cutting or stamping sections of the base 36 surrounding each pawl 35 to form openings 38 that define three edges and one principal surface of the pawls, and bending the pawls 35 inwardly about an upper edge or edges 39. The thickness of the pawls 35 is less than the thickness of the sleeve 31, so that the cuts do not extend to the exterior of the sleeve 31. As a result, the pawls 35 are not visible when the sleeve 31 is assembled to the main body 30.

In operation, when the sleeve 31 is rotated relative to main body 30 to move the window 34 from one of the numbers 33 to a higher one of the numbers 33, the pawls 35 are moved from one notch 37 aligned with one of the numbers 33 to an adjacent notch 37 aligned with the next higher one of the numbers 33. Single-direction rotation, i.e., ratcheting, is achieved as a result of the asymmetric shape of notches 37, which include a sloped surface 40 on one side and a perpendicular surface 41 on the other side. When the sleeve 31 is rotated in an incrementing direction, the pawls 35 exit the notches 37 by passing over the sloped exit surfaces 40. When the pawls 35 are within one of the notches 37, reverse rotation is prevented by engagement of edges of the pawls 35 with the perpendicular surfaces 41.

In addition, as illustrated in FIG. 5, the sleeve 31 is preferably retained on the main body 30 by cooperation between pawls 35 and an outwardly extending rim 42 that is shaped to allow the pawls 35 to pass over the rim 42 as the sleeve 31 is assembled to the main body 30 from below, and to prevent disassembly by engagement between bottom edges 43 of the pawls 35 with an upper surface of the rim 42, thereby eliminating the need for a separate fastener to secure the sleeve 31 to the shot glass main body 30.

FIG. 7 shows an initial position of the assembled main body 30 and sleeve 31, while FIG. 8 shows a subsequent position after the sleeve 31 and main body 30 have been rotated by a user from the initial position, in which the pawls 35 are position in notches 37, to a second position in which the pawls 35 have been moved to adjacent notches 37, incrementing the number 33 visible through window 34.

It will be appreciated that although the pawls 35 of this embodiment are illustrated as extending from an inner surface of sleeve 31, while the corresponding notches 37 are illustrated as extending from an exterior surface of main body 30, it is also within the scope of the invention to extend the pawls from the main body 30 and to form the corresponding notches on sleeve 31. In addition, it will be appreciated that the main body 30 and sleeve 31 of the embodiment of FIGS. 1-8 may be molded from a resin or plastic material, formed of cast or sheet metal, or made of any other suitable material or combination of materials without departing from the scope of the invention. Similar variations in pawl/detent and notch positions, and materials of the main body and sleeve, may also be made with respect to the embodiments shown in FIGS. 9-16, described below.

In the embodiment shown in FIGS. 9-13, pawls 35 and notches 37 of the first preferred embodiment are replaced by a stepped surface 11 on a bottom surface of a shot glass main body 1 and pawls or detents 7 on a top surface of a base 8 of sleeve 2.

In this embodiment, an externally threaded fastener 18 rotatably couples the main body 1 to the sleeve 2 by extending through a central opening 19 in a base 8 of the sleeve 2. The fastener 18 is threaded into internally threaded pillar 20, which extends from the bottom of main body 1 and through the central opening 19 to capture the base 8 of sleeve 2 between the bottom of main body 1 and a head portion 21 of the fastener 18, as best shown in FIG. 4. An exterior surface of the pillar 20 serves as a bearing surface that engages edges of opening 19 and about which the sleeve 2 rotates relative to the main body 1.

As illustrated in FIG. 10, a lower section 3 the main body 1 includes a series of numbers 4 similar to those of the embodiment of FIGS. 1-8, which are arranged around the external circumference of the main body 1, in an area covered by the sleeve 2. These numbers are positioned so that they can be viewed through a window 5 in the sleeve 2 when the sleeve 2 is assembled to the main body 1. As the sleeve 2 is rotated around the main body 1, different numbers will appear in the window 5, the adjacent numbers differing by 1 to increment the count appearing in the window as the sleeve 2 is rotated. Those skilled in the art will appreciate that the numbers 4 may take any form, including numbers that are engraved or physically formed in or on the main body 1, and/or printed, painted, silkscreened, or otherwise drawn on a surface of the main body, or provided in the form of stickers. In addition, it will be appreciated that the numbers are not limited to Arabic numerals, and that the numbers may further be replaced or supplemented by pictures or symbols that represent the effects or consequences associated with the number of shots that have been consumed.

Similarly to the embodiment of FIGS. 1-8, to ensure that the count is advanced by just one step each time the sleeve 2 of FIGS. 9-13 is rotated relative to the main body 1, and thereby make it simple for a user to increment the counter even when impaired or intoxicated, the shot glass of FIGS. 9-13 also includes a ratcheting mechanism, which in this embodiment is made up of a stepped surface 6 at the bottom of the main body 1, and corresponding detents or pawls 7 on an upper surface of base 8 of the sleeve 2. Each pawl 7 includes a vertical end surface 9 and an inclined surface 10, while the stepped surface 6 of the shot glass main body 1 includes spaced inclined surfaces 11, horizontal surfaces 12 extending from ends of the spaced inclined surfaces 11, and vertical surfaces 13 separating and extending between the ends of the horizontal surfaces 12 and the inclined surfaces 11.

The respective vertical surfaces 9 and 13 of the pawl or detents 7 and the stepped surface 6 are respectively aligned with the numbers 4 and window 5 so that, as the sleeve 2 is rotated relative to the main body 1, inclined surfaces 9 of the pawls 7 encounter and pass over inclined surfaces 11 on the base, resulting in an increased resistance to rotation that is felt by the user and maintained as the inclined surfaces 9 continue to pass over the horizontal surfaces 12 until the vertical surfaces 13 are reached. When the inclined surfaces 9 reach the vertical surfaces 13 upon continued rotation of the sleeve 2 relative to the main body 1, the resistance to rotation caused by passage of the inclined surfaces 9 over the horizontal surfaces 12 abruptly ends, providing feedback to the user that the window 5 has been moved to a next number 4, prompting the user to stop rotating the cup. In addition, the intersection between vertical surfaces 13 and inclined surfaces 11 forms an indentation 14 to bias the sleeve 2 in a position in which the window 5 is centered relative to one of the numbers 4, thereby preventing further relative rotation between the base 1 and the sleeve 2 until force is again applied by a user to intentional increment the count by rotating the sleeve 2 relative to the main body 1. Finally, the vertical surfaces 10 and 13 also prevent the sleeve from rotating in an opposite direction, so as to prevent the user from unintentionally decrementing rather than incrementing the shot count.

As illustrated in FIG. 12, the shot glass main body 1 is frustoconical in shape and also includes an upper section 15 forming a collar 16. The upper and lower sections 3 and 15 together form a continuous frustoconical inner surface 17. The outer diameter of the lower section 3 is reduced by an amount that is equal to a thickness of the sleeve 2, so that when the sleeve 2 is fitted over the main body 1 as shown in FIG. 12, the outer body of the shot glass also forms a continuous frustoconical outer surface.

FIGS. 14-16 show a third embodiment of the present invention, in which the sleeve of the first two embodiments is replaced by an annular sleeve 50 positioned in an annular groove 51 extending around a midsection of the shot glass main body 52. Pawls 53 in the sleeve 50 are arranged to engage notches 54 in the main body 51 to permit incrementing of numbers 55 display in window 56 in the same manner as with the embodiment of FIGS. 6-13. In this embodiments, the ratcheting effect is achieved by shaping the notches 54 so that they slope radially inwardly from a leading edge 57 to a perpendicular surface 58 on a trailing edge of the notch. Bottom edges 59 of the pawls 53 engage a horizontal shoulder 60 at the bottom of the circumferential groove 51 to allow the sleeve 50 to be snapped into and retained within the groove 51.

Operation of the sleeve of this embodiment to keep a shot count is the same as with the embodiments of FIGS. 1-13, with rotation of the sleeve 50 relative to the main body 52 causing the pawls 53 to move from notches 54 to adjacent ones of the notches 54.

FIG. 17 shows exemplary embodiment of the invention, in which the shot glass main body is replaced by a stem 60 of a marijuana pipe 61 having a bowl 62. The indicator is provided by numbers and/or drawings arranged around the stem, and a corresponding sleeve 63 having a window 64 through which one of the numbers, symbols, and/or drawings 65 may be viewed to indicate the number of hits consumed by the user. The sleeve 63 is rotatable relative to the stem 60 and preferably includes a ratchet mechanism, which can be similar to any of the ratchet mechanisms described above to prevent reverse rotation of the sleeve 63 and provide tactile feedback when the count has been incremented.

Although four embodiments of the invention have been described in connection with the accompanying drawings, it will be appreciated that modifications of the illustrated embodiments may be made without departing from the scope of the invention. For example, the shapes and locations of the pawls and notches that form the ratcheting mechanism may be varied in any way that still permits one movement of the sleeve relative to the main body, and stable positioning of the window relative to a number until the force is applied by a user to intentionally increment the number displayed in the window. The shape and size of the shot glass may also be varied, as may such mechanical expedients as the manner in which the sleeve is retained on the main body. As a result, the invention is not to be limited by the above description or the accompanying drawings, but rather is to be defined solely in accordance with the appended claims.
